Choosing the right hose for a gas water heater is not only a matter of ease of installation, but also of the safety of the entire system. The stable operation of the equipment and the protection of your home from dangerous situations depend on the quality and compliance of the product with standards.
A gas water heater requires both a gas connection and a water supply. Both types of hoses must be of high quality, certified, and meet standards.
Gas connection hoses to the gas column
What should a quality gas hose be like?
- Certified. Only products with marking and confirmation of conformity are allowed for use.
- Resistant to loads. A high-quality flexible gas hose withstands pressure and temperature changes.
- Flexible and durable. It should be easy to install without the risk of kinks.
- Reliable in connections. It is advisable to choose options with welded fittings.
Types of gas hoses
- Rubber reinforced. Budget-friendly, but short-lived.
- With metal braiding. Protected from damage, but the braiding needs to be monitored.
- Corrugated stainless steel gas hoses. Such hoses for connecting a gas water heater are considered the best option due to their strength and durability. The most reliable and safest products are those that comply with the European safety standard EN 14800.
Water hoses for gas water heater
In addition to gas, the column is connected to the water supply system. For this, water hoses for the gas column are used – flexible lines that provide cold water supply for heating and hot water drainage.
Types of water hoses
- Rubber in metal braid. The most common option, but lasts 3-5 years.
- Corrugated stainless steel water hoses. The most durable and reliable, withstand high pressure and temperature.
- Reinforced polymer. They have additional reinforcement, which extends their service life.
How to choose a water hose?
- Consider the diameter and thread of the fittings so that they fit your speaker.
- Choose a hose of the desired length (usually 0.5–1.5 m).
- Prefer models with stainless steel or brass connections that are not subject to corrosion.
Safety rules
When selecting and installing hoses, follow these recommendations:
- use special gas hoses for connecting to gas and water hoses for the gas column for connecting to water;
- do not confuse them – gas and water have different characteristics and markings;
- avoid strong bending and stretching;
- Trust the installation to professional craftsmen.
Conclusion
Two types of hoses are required to connect a gas heater:
- for gas – corrugated stainless steel hose (for example, Eco-Flex Gas Euro EN14800);
- high-quality water hose (braided or corrugated stainless steel) – for connection to the water supply system (for example, Eco-Flex Water Standard or Eco-Flex Water Super).
Together, they will ensure the reliability, safety, and durability of your gas water heater.
